Answer: hello your question lacks the options related attached below is the complete question

answer :

A brief positive current inward due to sodium entry through voltage gated sodium channels ( Option 4 )

Explanation:

What you would expect to see following the bathing of a sensory neuron in  tetra ammonium chloride and MgCl2, given that the voltage clamp moves from -70 to -5 mV is A brief positive current inward due to sodium entry through voltage gated sodium channels.

This is because as Cl^- enters the cells it causes the entrance of  Na^+ into the cell ( i.e. voltage gated Na^+ ions channels will open ) hence the mixture will cause a lower negative membrane potential to be present .

Andre45 [30]

The principal money Mrs Karki deposited in the bank was

= Rs 1339

Simple interest (Si) received = Rs 4,740

Time (t)= 6 years

Rate (r)= 59%

Therefore the principal amount (p) =

p = \frac{si \times 100}{r \times t}

where,

p =  \frac{4740 \times 100}{59 \times 6}

p =  \frac{474000}{354}

p = 1339

Therefore, the principal money Mrs Karki deposited in the bank was = Rs 1339

Scientists studied reproduction in the New Zealand mud snail. They wanted to determine whether reproducing sexually or asexually
lubasha [3.4K]

A hypothesis is a claim that expresses a relationship between variables. D) Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.

<h3>What is a hypothesis?</h3>

A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, but not a fact. It is a claim of how it works a relationship between two or more variables.

The researcher hypothesizes in order to predict what is going on or what is expected to occur.

A hypothesis must express what is expected to occur in a perfectly comprehensive manner. There must be a logical relationship between the involved variables. It must be objective. Usually, it is written in the present time.

There are different kinds of hypotheses: descriptive, correlative, differentiative, or causative.  

In the exposed example, researchers wanted to determine whether reproducing sexually or asexually was more beneficial for the snails.

Options,

A) <em>Sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation. </em>

The benefit of reproducing sexually is that the risk of mutation is lower.

B) <em>Asexual reproduction is advantageous over sexual reproduction because it allows the snails to produce more offspring.</em>

<em />

The benefit of reproducing asexually is that a higher number of descendants are produced, which increases reproductive success.

C) Sexual reproduction is advantageous over asexual reproduction because it allows for snails to have increased genetic variation.

The benefit of reproducing sexually is that it increases genetic variation.

D) Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.

The benefit of reproducing asexually is that there is no need for social interaction.

Social interaction does not really benefit snails as a species. This is not a variable that might influence in a significant way snails.

However, variables like the mutation rate, variability, and the number of descendants are useful to test how they benefit or not the snails.  

The hypotheses that would least likely aid the scientists to answer the question is <u>option D</u>.
